BACKGROUND OF THE INVENTIONThis invention relates to surgical dressings and, more particularly, to surgical dressings in the form of booklets made to carry the electrical leads of a pacemaker tucked into pockets formed by pages of the booklet or wrapped around notches disposed in the ends of the booklet pages so that such leads are separated by the pages of the booklet and remain tangle free and available for rapid insertion into a mechanical device to stabilize a faltering or accelerating heartbeat following surgery, and more particularly, heart surgery.
At the present time following open heart surgery, electrical leads will be surgically attached to a patient's heart and left protruding from an opening in the patient's chest so that such leads can be inserted into a pacemaker or monitoring machine if the patient's heartbeat is fibrillating or faltering so that external means can be used to stabilize the heartbeat without resort to additional surgery to reopen the chest cavity. Typically, each opening in a patient's chest will carry both a positive and a negative wire, and incisions might be made under each rib cavity so that a patient would have four wires dangling from his or her chest. Such leads are inconvenient and unsightly and frequently tangle or pull. They may require manual separation if it becomes necessary to attach the leads to a pacemaker machine.
The present invention responds to the disadvantages set forth above by employing a dressing in booklet form which receives and separates the negative and positive wires protruding from the patient's chest and stores them in pockets formed by the pages of the dressing or, alternatively, by coiling them around notched pages of the dressing so the leads are neatly separated and quickly inserted into the negative and positive receptacles of a pacemaker machine.
Additionally, the dressing of the present invention is easy to assemble and requires a minimum of labor, thereby making the dressings inexpensive to manufacture and dispose after use.
OBJECTS OF THE INVENTIONIt is, therefore, the primary object of this invention to provide a surgical dressing which is neat in appearance and offers an answer to the dangling pacemaker wires heretofore a familiar result of heart surgery.
It is a further object of this invention to provide a surgical dressing which separates the wires extending from the chest cavity and keeps them available in pockets or pages for immediate access and insertion into a pacemaker receptable.
A more particular object of this invention is to provide a surgical dressing, as aforesaid, which is lightweight and convenient to use and fasten, yet renders the pacemaker wires readily accessible and is disposable after use.
Another object of this invention is to provide a dressing, as aforesaid, wherein the pages of the dressing are collapsibly stacked upon closure of the booklet, so the booklet can be secured at the open end by means of a fastener, to ensure capture of the coiled wires.
Yet another object of this invention is to provide a dressing, as aforesaid, wherein the dressing is made of inexpensive material such as cheese cloth or gauze fabric, and employs hem stitching around the edges thereof to prevent raveling yet reduce cost of manufacture so that the dressings are readily disposable and can be discarded after use by a patient.

FIG. 3 is a top plan view of the dressing closed left to right with the fastener in place and the pacemaker wires enclosed in the envelope with their ends visible at the top right of the closed dressing.
FIG. 4 is a perspective view of two closed dressings in place against a patient s chest with the ends of the pacemaker wires protruding from the patient's body and enclosed by the surgical dressings of the present invention.
FIG. 5 is a perspective view of an alternative embodiment of a dressing disposed in booklet form with its inner pages open to reveal details of construction and placement of the end fastening devices.
FIG. 6 is a top plan view of the embodiment of FIG. 5 showing the inner pages flat against the covers and pacemaker wire coiled around the right page of the booklet and secured by a fastener, with the left page revealing an inner velcro fastener in open position and an additional velcro fastener in open position extending from the right-hand cover.
FIG. 7 is a top plan view of the dressing of FIGS. 5 and 6 closed, with the booklet shut and the end fastener in place to secure the wrapped pages.
FIG. 8 is an edge elevation of the closed dressing of FIG. 7, each notched page being wrapped with a pacemaker wire in the sandwich or booklet configuration shown.
DESCRIPTION OF THE PREFERRED EMBODIMENTReferring to the drawings, FIG. 1 shows abooklet dressing 10 with theouter cover pages 12 and 14 in a flat position. Theinner pages 16 and 18 are divided by a line offold 20 formed by stitching through the middle of the double thickness ofrectangular piece 22 laid on top ofrectangular piece 15. The combined pieces are then bound together at the top and bottom edges ofpieces 15 and 22 with stitching 23 to form pockets orcompartments 24 accessible from the outer orshort sides 25 of thebooklet dressing 10.
Acoiled pacemaker wire 26 is shown in FIG. 1 to the left of thedressing 10 in removed position with the lead orprobe 28 visible inside the coil.
The separation of the sandwichedrectangular pieces 15 and 22 is further demonstrated in FIG. 2 where negative andpositive pacemaker wires 26 are shown within thepockets 24 by use of phantom or broken lines.
Thefastener 30 that closes thebooklet 10 is shown in FIG. 2 extending from the right of the righthand compartment orpocket 24.velcro fastener 32 can be used at the end offastener 30 as the preferred closure means although any other simple, low-cost means of closure could be used.
When thecompartments 24 of thedressing 10 shown in FIG. 2 are folded left to right with thecoiled wires 26 therein, the closedbooklet 10 is as shown in FIG. 3. Although FIG. 3 shows thewires 26 extending from the same corner, in actual use it would be preferred that thewires 26 be coiled so that theleads 26 are separated by thefastener 30 for ease of connection, but the details of separation can be dictated by the user.
The envelope orbooklet 10 would be taped to the patient's chest by means of transparent tape (not shown), preferably with thefasteners 30 toward the patient's body rather than facing out as shown in FIG. 4, so that the tape anddressing 10 could be lifted and removed as a unit and thewires 26 extracted from the respective pouches orpockets 24 without the necessity of undoing thefastener 30.
FIG. 5 shows an alternative embodiment of thedressing 10, the leads orwires 26 being separated in this embodiment by inner compartments orpages 32 with anadditional divider page 34 serving to further divide the negative andpositive wires 26. In this embodiment thewires 26 are wrapped around thepages 32 as shown in FIG. 6, usingnotches 36 in the top andbottom edges 38 ofpages 32 as guides or holders and then, securing, theleads 26 by means offasteners 40 with VELCROfastener tabs 42 which are attached medially topages 32 and close horizontally across theleads 26 where they are mated with VELCROfastener tabs 44.
Thedressing 10 of FIG. 6 is substantially similar to thedressing 10 of FIG. 3 when the covers are closed left to right, but theleads 26 will be extending from the top orbottom edges 38 of dressing 10 rather than the corner when thedressing 10 is in closed position. Theprobes 28 can be tucked under laps of the wrappedleads 26.
When viewed from the edge as in FIG. 8, thedressing 10 of FIG. 6 can be seen with thewires 26 in wrapped position and thedivider page 34 of FIG. 5 shown sandwiched between thepages 32.
Thedressings 10 may be made of gauze, cheesecloth or other lightweight, non-allergenic material and may be taped to a patient's chest by use of transparent tape (not shown) of sufficient size to cover theentire dressing 10. If thewires 26 of thedressing 10 must be removed from thedressing 10 for attachment to an external pacemaker or other monitoring machine, the tape anddressing 10 can be lifted from the patient's chest and thewires 26 extracted without wasted effort or delay.
All edges of thedressing 10 may be sewn to eliminate raveling, but as is apparent from the drawings, the preferred embodiment of FIGS. 1 and 2 requires less stitching and does not employinner fasteners 40 and thus is less expensive to manufacture than the embodiment of FIGS. 5 and 6.
